Myths Randomness House advantage Skill vs. Game House advantage, with optimal play Baccarat 1. Skill vs. Player assessment quiz. Of course, these probabilities are a critical determinant of the house advantage — that is, the long-term price of the wager. This rare ability to hide the price of a good or service offers an opportunity for casino management to raise the price without notifying the players — if they can get away with it.
If players are able to detect these concealed price increases simply by playing the games, then they may choose to play at another casino. This terrifies casino operators, as it is difficult and expensive to recover from perceptions of a high-priced slot product.
Consequently, many operators resist increasing the house advantages of their slot machines, believing that players can detect these price shocks.
Our new research , however, has found that increases in the casino advantage have produced significant gains in revenue with no signs of detection even by savvy players. In multiple comparisons of two otherwise identical reel games, the high-priced games produced significantly greater revenue for the casino. These findings were confirmed in a second study.
Further analysis revealed no evidence of play migration from the high-priced games, despite the fact their low-priced counterparts were located a mere 3 feet away.
Importantly, these results occurred in spite of the egregious economic disincentive to play the high-priced games. That is, the visible pay tables were identical on both the high- and low-priced games, within each of the two-game pairings.
And that is the appeal of slots, to casino manager and jackpot hunter alike. Something to remember, because no matter how lucky you feel, eventually the casino will get luckier. Have fun playing slots, but remember, they don't build all this by giving money away.

We'll also see what determines the odds of winning on a slot machine and look at some popular variations on the traditional game. The classic slot machine design works on an elaborate configuration of gears and levers. The central element is a metal shaft, which supports the reels. This shaft is connected to a handle mechanism that gets things moving. A braking system brings the spinning reels to a stop, and sensors communicate the position of the reels to the payout system.
A coin detector initially registers that a coin has been inserted and unlocks a brake so the handle can move. There are any number of ways to arrange these elements, and manufacturers have tried dozens of approaches over the years, so we'll focus on one representative design.
The basic design includes three reels mounted on a central shaft. The central shaft also supports three notched discs , which are connected to the three reels. A second shaft below the central shaft supports a kicker , a piece of metal comprising three paddles. The kicker paddles are lined up so they can push against the notches on the three discs. The second shaft also supports a series of connected stoppers , teeth that lock into the notches on the discs. The kicker and the stoppers are both connected to springs, which hold them in a standby position.
The kicker is held in place behind the discs, while the stoppers are held up against the discs, locking them into place. When you pull the handle on a slot machine, these parts do a lot of work. We'll look at exactly what happens in the next section. A series of events takes place after a person pulls the handle on a slot machine. Here's a rundown:. From the player's point of view, here's how it looks.
The player pulls the handle. There is a clunk, and the three reels start spinning. Then the three reels stop abruptly one at a time, followed by the payout if necessary. The "stopping one at a time" part builds suspense. If the first reel stops on the jackpot symbol, then you have to wait for the next reel to stop to see if it is a jackpot, and then finally the third.
If all three display the right symbol, the player wins. Conventional mechanical slot machines eventually gave rise to electrical machines that worked on similar principles.
In an electrical machine, the reels are spun by motors and the stoppers are generally activated by solenoids , but the game basically plays out the same way.
Electrical machines have more sophisticated money-handling systems, like those you might find in a vending machine, and flashier light and sound displays. In both types of systems, once the reels have come to a stop, the slot machine needs to read whether the player has won or lost. In the next section, we'll examine some systems for making this determination. There are dozens of different payout systems used in slot machines. In one of the simplest designs, a jackpot is detected by measuring the depth of notches in the discs that drive the reels.
For simplicity's sake, we'll look at this sort of payout system in a bare-bones slot machine. The machine only accepts one kind of coin, and there is only one winning combination of images. When you put a coin in this machine, it falls into a transparent case. The bottom of the case is a movable shutter that is connected to a metal linkage, as you can see in the diagram.
Normally, the linkage holds the shutter closed. But when the machine hits the jackpot, the third stopper shifts the linkage up, opening the shutter so the coins fall out of the machine.
Each of the three discs has notches for each stop position of the reel. The notch for the jackpot stop is deeper than the other stops. Consequently, when the first reel lands on the jackpot stop, the first stopper moves farther to the left than it would for any other stopper. If the second reel stops on the jackpot as well, the second stopper also moves farther left. Same goes for the third reel and stopper.
But if only the second reel stops on the jackpot, the second stopper will not move all the way into the notch. The first stopper has a catch that keeps the second stopper from moving past it.
